COMBINED CHAIR AND DESK ATTACHMENT.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed February 18, 1910. Serial No. 544,538.

To all whom it may concern:

Be it known that LJosnPn E. Buncn, a citizen of, the United States, residin at Denver, in'the county of Denver and tate of Colorado, have invented certain new and useful Improvements in Combined Chair and Desk Attachments, of which the following is a specification.

This invention relates to combination fur-.

niture in the form of a desk and seat and more particularly to a device of this character adapted for the use of stenographers, and the invention has for its object the provision. of a combined seat and typewriter stand attachment, though I wish to reserve the right to manufacture the chair indendent of the stand, whereby the chair may used as an ordinary ofilce chair.

' An object of the invention is to provide a device of this character in which the stand I to be in a chair for any length of time.

A further object is the provision of a desk or stand attachment and novel means for securing the same to the chair, so as to do away with an expensive desk andv chair,

at the same time providing a' device which will be complete in itself, so positioning the stationery, letters, note books and other necessaries, in convenient position to the operator for use. A still further object is the provision of a device which can be constructed of a minimum amount of material, so as to take up a small amount of space, and which can be constructed at a low cost.

Other objects'and advanta es will be aparent from the following escription and it will be understood that changes in the specific structure shown and described may be made within the scope of the claim without departing from the spirit of the invention.

In the drawings: Figure 1 is a perspective view showing the desk and seat secured in position for use, and also showing the attachments thereto, by which the stationery and the like are supported for ready use. Fig. 2 is an underside view of the seat showing the spring cushion attachment thereto. Fig. 3 is a vertical central sectional view of the supporting member for the seat,-showing the relative connection of the parts and the interior supporting spring. Fig. 4 is a detail view of the standard showing the position of the grooves thereon, said rooves being adapted for engagement with the movable upper portion carried by the seat. Fig. 5 is a detail view. of a sleeve for adjusting the vertical position 'of the spindle. Fig. 0 is a detail view showing the manner of pivoting the upper portion of the arm extension of the stand to the lower portion thereof. Fig. 7 is a view of the under side of the desk board, showing its attached parts in different relative positions and the supporting arm in section; Fig. 8 is a central longitudinal sectional view of the spring cushion attachment, detached from the seat.

In the drawings I have shown a seat 10, to the. under side of which is secured a depending bracket 11, which comprises a. base portion which is positioned parallel with relation to the bottom of the seat and has its central portion cut away as shown at 12, longitudinally thereof, the tongues formed by said cutaway portion being extended inwardly for engagement. with the bottom face of the seat. The said inturned portions form ribs adaptcdlo brace the bracket adjacent the sides of the openings, said inturncd portions 13 being positioned in enga ement with the under face of thc'seat am secured thereto through the medium of ,thc outturned portions 14, the ends15 of 'the brackets being extended upwardly at 'an angle to the central portion and said ends are provided with apertures through the medium of which said bracket is secured to the seat, and as also shown one of the ends is provided with an opening communicating with the central opening of the bracket, said opening being adapted to receive a suitable spring 16 when in position, aswill be hereinafter more fully described.

Pivotally secured to a transverse rod mounted on the inturned portions of the 45 lower' portion'of the sleeve is' hollowed a bracket centrally thereof, is an intermediate arm 17, said arm having upturned flanges 1? which are pivotally engaged with the plvot rod and are adapted to ride within the slot. The base of saidintermediate member is provided with a downwardly extended. arm orextenslon 19, said. arm being prQ- at its restricted end so as to resist theweight of a person when seated in the chair. The arm 17 is further provided with a slotted opening communicating with the central openin in the bracket, and it will be seen that w im the spring is in position and under the weight of a person sitting in the chair, thearms of said spring will be compressed and forced into these openings allowing sutiicient movement to the parts when under a severe strain, though it is to. be understood that the resiliency of this spring is such as to permit free and even movement of the parts of the chair when the same are under a strain or released there; from.

The base of'the arm has secured thereto 21 depending stem 23, whichis provi'ded with an enlarged or flared upper portion24, adapting. the same to be secured tov said base portion, and as shown, I have provided this flared portion with openings through which the fastening means can be passed into engagement with the base portion, whereby said parts are rigidly heldtogether. This depending stem 23 is screw threaded, a

greater portion of its length, andis received within an opening in the upper partof the sleeve, the upper portion 26 of which is formed of solidinnterial, with the exception of the opening through.said'portion into which the stem 23 is adapted to work. The

greater portion of. its interior diameter and has inwardly extending lugs 97 for cnga ement with; the grooves 28, formed in t e' upwardly. extending stem 2-9, said grooves extending vertically of the opposite sides of'the sleeves and terminating short of both ends thereof, 'said' grooves being also extended at-ri'ght angles adjacen't to the up- "per ends thereof, one quarter of the distance around the sleeves and. then upwardly rto the end of the cylinder, it being apparcut that the lugs 27 will be applied simultaneously to said grooves and slid thereinto for positioning the sleeves 25 and the seat carried thereby onto the stem 29, saidlugs being prevented from withdrawal therefrom when lifted vertically, but being removable through the medium of the right angular 'extemled portion. The. upper end of the of theseatand this stem is engaged by t e adjustingfnut "31, movable thereon and adapted to adjust the hei ht of the chair seat, it being understood t at such adjustment is regulated by the posi'-' tion of the nut on the stem, so that further downward movement thereof is prevented This nut has a fiang'ed rini; at itslower end which rests uponj the lip30,"said nuts;

being formed in two parts hinged togethj arv upon op osite sides, so that thexs'amefi ai be readi' y applied to or removed from the sition they are secured by means of "set screws, the flanged portion thereof being adapted to titu'nderv the edge 'ofi 't he'lip so as to prevent the chair from being pulled stem and when said parts are in closed poapart when lifted. The sleeve portion of I screw threads engageable with the screw threads on the stem Said sleeve is pro- .vided with .a Set screw- 32 extending-transversely therethrou h to engage w th. the screw threads on the stem, whereby it can be held in any position onr the stem and the stem thereby held ,insuch position. It is understood that when -it is desired-to raise the adjusting nut, isprovided'with' internal orlowerthe chair the adjusting screw is rotated for disengagement with'the threads on the stem 93, whereby the member 23 may be moved to any desired position within the sleeve 33 and held by means of the set screw,

it being understoodthat the flanged per, .tion 31 may be retained into engagement 105.

with the lip 30 formed on the upper end of the sleeve'25; a Y

The lower end oft-the stein 29 is enlarged I for a portion of its length, as shown at 34.

and said enlarged portion is provided at equal distances around its periphery, with outwardly extending sockets 35, said sock- -ets being secured to or formed integral with.

the front portion 34 and have receivedtherein the usuallegs 36. I have provided four of such legs. though'any number thereof may be provi'ded and the outer endsthereo-f have the usual rollers 37, so that the chair may be readily moved about the'floon. The

stem 29, above the enlarged portion 34, is

hollowed out from its upper end, as shown at 38, an'd'a coil-spring 39 is disposed therein, around the depending stem 23,";said

spring being positioned. intermediate the sleeve 25 and the'b'ottom. of'the hollowed;

out POItlOI-I'Df the stem, -soasfto hold the sleeve. in a normally distended position, the inward'lvextended lugs 27 being adapted to slide within'the grooves 28 upon relative movement ofthe'two parts. Fitting'snuglv into the top of the stem 29 is a ring 6, said so as to fit closely within the sleeve 25, to

take up wear upon the parts and to prevent wabbling' thereof.

Disposed above the enlarged portion 34 of the stem, is a collar 40, said collar being disposed around the stem below the sleeve 25 and adapted to rest upon a shoulder formed by the enlarged portion 34 .with the smaller portion of the stem, and as said parts are preferably of cast material, it is more especially desired that the upper face of this enlarged portion forming the shoulder, be formed with a polished bearing surface for the collar 40, which is adapted to move thereon and said collar has secured thereoyer and disposed upon the stem 29, a securing sleeve 41, which is positioned to contact with the upper edge of the collar 40, to securely hold the same in its lowermost position and in contact with the shoulder, so that the stand casting 42 formed therewith will be held against play thereon. This at and casting 42 is rotatable on the stem 29, through the medium of the collar 40. and is 4 in the form of an arm extending outwardly from the collar and curved downwardly so as to posit-ion the same near the floor, said arm is then extended upwardly a proper dis tance, the upper end of said arm being bifurcated for the reception of the lower end of the standard connecting portion 43. At a point on the casting, adjacent to the floor, two feet 44 are secured on either side thereof, said feet beinp secured to the casting in any desirable manner. the lower ends of the feet being provided with the usual hearing rollers. so as to allow, the casting to be moved to any desired position. The object of the feet is to prevent the weight of the typewriter supporting stand from overturning the chair.

'lhe bifurcated arms have their interior side faces notched as shown at 46, and said arms are, provided with registering openings extending transversely therethrough. said openings being adapted toreceive a suitable securing bolt-47, which is,

also passed through the lower notched end of the connecting standard 43. Thelower end of the connecting standard 43 is reduced laterally to form a tongue 48, which. asbefore mentioned, is notched upon either side thereof. all of said notches being disposed in a circular position around the openings. with which the tongue 48 is also provided.

7 and the bolt is provided with a securing: nut

49. so that bv rotating said nut in one d rection the forcive contact of the notched faces will be lessened and the connectin standard 43 may be swung at any desired angle relative to the armor casting-hut still be held in a very rigid position.

Secured to the outer flared end of the con necting portion 43 is a desk board 50, upon which the typewriter is adapted to be sup ported and held in a rigid position in the usual manner. The desk board has secured to its under surface adjacent said end. a collapsible frame, said frame being composed of a plurality of bars 52 extending outwardly therefrom, a plurality of cross members 53 provided therefor centrally thereof and at each end, said parts being pivotally connected where crossed, the frame bein pivotally mounted at the side of the board. so that the same may be folded and slid under the stand. On the left hand side of ,the board is a similar but smaller frame 51.

it being understood that a basket or a board for holding mail or other papers may 'be supported thereon, when extended. Secured to the under face of the board adjacent the left hand side and at the forward end thereof, is a box 54 which is pivotally secured thereto and adapted to be swung outward, this box being adapted for the reception of pens, pencils, etc. Disposed at the right hand corner of the board and adapted to be pivoted in a similar manner to said board is a case which extends over the greater portion of the board, this case being prefer ably constructed of metal and divided into compartments, for the reception of writing material, etc. y

The manner of adjusting the seatand the desk board. having been previously described, it will thus be seen that I have provided a cushion frame chair and stand at tachment. which will do away with the use of an expensive desk and chair. the device beirn, so complete in itself that there will be no need of other furniture or place for handling the work. the operator being able to keep stationery. letters. note books. pencils, and all other necessaries in a position to be readily procured when desired.

I wish to have it understood that I may manufacture this device with or without the stand attachment, it; being understood that the same may be manufactured in sizes to suit the requirements. that is; whether used as a. stenographers chair or as an ordinary, ofiice chair, though I wish to have itunderstood that the same principle may be applied toany form of chair.

What is claimed is? A tilting chair comprising a seat. a bracket formed from a single piece of metal and comprising a base portion being cut.-
